2017-02-06mtd: nand: ifc: Fix location of eccstat registers for IFC V1.0Mark Marshall
The commit 7a654172161c ("mtd/ifc: Add support for IFC controller version 2.0") added support for version 2.0 of the IFC controller. The version 2.0 controller has the ECC status registers at a different location to the previous versions. Correct the fsl_ifc_nand structure so that the ECC status can be read from the correct location for both version 1.0 and 2.0 of the controller.

2016-04-19mtd/ifc: Add support for IFC controller version 2.0Raghav Dogra
The new IFC controller version 2.0 has a different memory map page. Upto IFC 1.4 PAGE size is 4 KB and from IFC2.0 PAGE size is 64KB. This patch segregates the IFC global and runtime registers to appropriate PAGE sizes.

Freescale's QorIQ T Series processors support 8 IFC chip selects within a memory map backward compatible with previous P Series processors which supported only 4 chip selects. Signed-off-by: Aaron Sierra <asierra@xes-inc.com> Signed-off-by: Brian Norris <computersforpeace@gmail.com>
2014-09-03fsl_ifc: Fix csor_ext position in fsl_ifc_regsAaron Sierra
According to Freescale manuals, the IFC_CSORn_EXT register is located immediately _after_ the bank's IFC_CSORn register. This patch adjusts the csor_ext member of and reserved register arrays immediately surrounding the csor_cs structure to provide proper access to this register.

2014-02-18driver/memory:Move Freescale IFC driver to a common driverPrabhakar Kushwaha
Freescale IFC controller has been used for mpc8xxx. It will be used for ARM-based SoC as well. This patch moves the driver to driver/memory and fix the header file includes. Also remove module_platform_driver() and instead call platform_driver_register() from subsys_initcall() to make sure this module has been loaded before MTD partition parsing starts.
